[−][src]Trait influxdb::Query

pub trait Query {
    fn build(&self) -> Result<ValidQuery, Error>;

    fn get_type(&self) -> QueryType;
}

Required methods

fn build(&self) -> Result<ValidQuery, Error>

Builds valid InfluxSQL which can be run against the Database. In case no fields have been specified, it will return an error, as that is invalid InfluxSQL syntax.

Examples

use influxdb::{Query, Timestamp};
use influxdb::InfluxDbWriteable;

let invalid_query = Timestamp::Nanoseconds(0).into_query("measurement").build();
assert!(invalid_query.is_err());

let valid_query = Timestamp::Nanoseconds(0).into_query("measurement").add_field("myfield1", 11).build();
assert!(valid_query.is_ok());
